Rockfleet Castle has four floors and is over eighteen metres in height.
It is no longer open to the public for safety reasons.
The castle was installed with a metal walkway in 2015, from its adjacent grassland surrounding to its door due to the sheer inconvenience of accessing its entrance during high tides. Local legend has it that treasure once housed in the castle is now buried in an unknown location somewhere in the surrounding fields. If found, the individual who exhumed it is said to be met by the Headless Horseman resulting in dire consequences.
